Sidney, I've not used nolvadex & this is purely off the top of my head, if you were using it to be in shape for a contest that would be one thing, but I'm not keen on the idea of blocking estrogen long term (I presume you are considering using it as a way of keeping bodyfat down)As far as I know nolva blocks estrogen in some tissues, (eg breast tissue) & is estrogenic in other tissues (eg bone tissue) I'm not sure what the effect on your own estrogen production would be.I think nolva is also quite hard on the liver. Maybe The Doctor could give us something a bit more concrete to go on?

The side effects of Nolvadex are usually low in dosages of up to 30 mg/day In rare cases nausea, vomiting, hot flashes, numbness, and blurred vision can occur. In women irregular menstrual cycles can occur which manifest themselves in weaker menstrual bleeding or even complete missing of a period. Women should also be careful not to get pregnant while taking Nolvadex. It is important for fe-male athletes that Nolvadex and the "pill" not be taken together since the antiestrogen Nolvadex and the estrogen-containing pill nega-tively counterfeit each other
